I have a friend who's due with her second baby in a few short months. She e-mailed me about finding a pump with horns large enough for very large breasts. She tried to pump with her last but she never had much success which she attributes to the horns her pump had.
I had an LC friend looking into this but I haven't hear back in a few months and I don't want to be giving the advice a week before she's due.
She nursed/pumped for about 4 months with her first dd and was sad and frustrated that she didn't have more success than that. I believe her workplace is very pump-friendly so I'd like to help her out.
